■ Hydraulic Oil Level
The hydraulic oil level gauge (1) is on the side of
the hydraulic oil tank (2).
The gauge shows the actual level of oil inside the
hydraulic oil tank.
Read it only when the booms are completely
down and completely retracted. Otherwise, the
boom hydraulic cylinders become large
reservoirs for hydraulic oil and the oil level in
the tank will be low.
The oil level (3) should be between the HIGH
mark and LOW mark.
■ Hydraulic Oil Temperature
The hydraulic oil temperature gauge measures
the temperature of the oil in the tank. The
temperature should not exceed 200°F (93°C). If it
does, reduce your driving speed or stop the
engine and let the hydraulic oil cool.
■ Temperature
The temperature gauge shows the temperature of
the water antifreeze mixture as the mixture enters
the engine block.
The typical operating temperature range for
FORD engines is 160°F to 190°F (71°C to 88°C).
The typical range for Kubota engines is 180°F to
205°F (82°C to 96°C).
